Hi @Kumar9024021 ,
Could you please share a bit more about your scenario?
Do you want the Button outside the View Form to be fixed to the View Form rather than the View Screen?
Based on the needs that you mentioned, I assume that you want the Button outside the View form to be fixed to the View Form rather than the View Screen, is it true?
I have made a test on my side, if you want the Button outside the View form to be fixed to the View Form rather than the View Screen, I afraid that there is no way to achieve your needs in PowerApps currently.
Actually, the X or Y property value of the Data cards in your Edit form would not be changed when you scroll down the View form, so you could not change the X, Y property value of the Clickable Button dynamically based on the X, Y property of any data card in your View form.
If you would like this feature to be added in PowerApps, please consider submit an idea to PowerApps Ideas Forum:
https://powerusers.microsoft.com/t5/Power-Apps-Ideas/idb-p/PowerAppsIdeas
As an alternative solution, you could consider add a "Custom data card" within your View Form, then add your Clickable button within this Custom data card, then you could execute the formula when you press the button.

After that, you could also re-order the custom data card in your View Form to a proper position.
Please consider take a try with above solution, check if the issue is solved.
Best regards,
